lnBikeShop showcases how a multi-application, service-oriented architecture can be structured around a clean, modular, and production-ready foundation. Using Spring Boot, Angular, JWT security, MySQL, Liquibase, MapStruct, Hazelcast caching, and service discovery through Consul, it demonstrates practical patterns for gateway routing, domain separation, and communication across services. Supported by a fully containerized Docker environment—including independent databases, centralized configuration loading, and a Prometheus–Grafana monitoring stack—lnBikeShop provides a comprehensive environment for evaluating microservice design, distributed workloads, and integration strategies in a manageable and technology-centered setup.
